Gravity
What is the force of gravity on Earth?
~9.8 m/s2
What is the primary factor that controls ocean currents on the surface?
Wind or the coriolis effect.
What are the three main scales for measuring temperature?
Celsius, Farenheight, Kelvin
What chemical bond results in the sharing of electrons?
Covalent bond
What are the four main macromolecules?
Carbohydrates, lipids, proteins, and nucleic acids.
What two variables determine the strength of gravity on an object?
Mass and distance between objects.
What is a name for the system of ocean currents the drives water around the globe?
The global conveyor belt or thermohaline circulation.
What are the primary factors that influence weather conditions? (Name at least 4)
Temperature, air-pressure, humidity, wind, and cloudiness.
How does an atom result in a cation?
When an atom loses one or more electrons.
What macromolecule is produced by the ribosomes?
Proteins
Explain how planets constantly rotate around a star without being pulled in.
A star's gravity pulls the planets inward, but the planets' inertia keeps it moving forward, resulting in a curved path. (orbit)
What is the correlation between ocean currents and climate?
Ocean currents transfer heat from warmer areas to colder areas and vice versa, which raises or lowers the temperature in these areas.
How does a cold front form?
When a cold air mass displaces warm air mass causing the warm air to rise above the cold air.
What results when a carbon atom gains two neutrons?
Carbon-14 (14C)
Give 5 examples of foods with nucleic acids.
Answers will vary. (5 things that were once living.)
How many times smaller is the gravity on the moon (1.62 m/s2) than it is on Jupiter? (24.79 m/s2) Round to the nearest tenth.
~15.3 times smaller.
What is the deepest point of the ocean, and what is the depth? (Round to the nearest hundred in feet or meters.)
The Mariana trench is ~36,200 feet or ~10,900 meters.
How do clouds form?
When warm air rises through convection and cools, which then condenses into water droplets and ice crystals. These clump together to form clouds.
Give an example of an ionic bond.
Answers will vary. Common bonds include NaCl, KCl, MgO, and CaCO3.
If a snake with red eyes (r recessive) and green scales (G dominant) produces offspring with a snake with red eyes (r recessive) and yellow scales (g recessive), what are the possible genotypes for the offspring and the proportions?
Where did Issac Newton go to college?
University of Cambridge
What would be the outcome for the north Atlantic region if the Gulf Stream stopped flowing?
Coastal North America and Europe would drop significantly in temperature, weather patterns would shift, and sea levels would rise.
What are the differences between a high pressure and a low pressure system. (Be clear with your description)
High pressure systems typically have sunny conditions and have descending air with outward flow, while low pressure systems include cloudy weather and precipitation, while also involving rising air with inward flow.
What is the attractive force that keeps chemical bonds together?
Electrostatic attraction
What are the names of the four letters in the DNA code?
Adenine (A), thymine (T), guanine (G), and cytosine (C).
